UltraPro Personal Security Window and Door Alarm, 6 Pack, DIY Protection, Burglar Alert, Wireless Chime/Alarm
Quick take
The UltraPro 6-pack is a DIY window and door alert system designed to add an audible deterrent and awareness layer without apps or monthly fees. It uses magnetic contact sensors and runs on four included LR44 batteries per alarm, with a switch to choose either a chime-style alert or a loud siren. The big caveat is that buyers consistently describe the “chime” as very loud and high-pitched, so it may not feel unobtrusive during daily life.
Pros and cons
Pros
- 120dB audible alert: designed to be heard from other rooms when doors or windows open.
- Simple chime vs alarm control: a side switch lets you match alerts to different situations.
- Wireless DIY installation: mounts indoors with included double-sided tape, no tools required.
- Works on more than just doors: also suitable for cabinets, drawers, and interior entry points.
Cons
- “Chime” can be too intense: some buyers call it a screech rather than a mild notification.
- Indoor mounting only for setup: alarms need to be installed indoors, which may affect placement options.
- Not a smart, app-based system: it is not smart home compatible, so it will not provide notifications to a phone.
What buyers think
Buyer-review evidence centers on three themes: how loud the alerts are, how easy the alarms are to set up, and whether the chime mode is truly “gentle.” Many people report the alarm is loud enough to be heard clearly at a distance, describing it as capable of startling someone opening an entry point. Setup is consistently described as quick, with tape-based mounting and straightforward battery access. The most recurring drawback theme is that the chime is very high-pitched and attention-grabbing, to the point that some buyers plan to use it less often than expected.
How this DIY alert system works
Each unit is a contact sensor setup. When the door or window separates from the magnet, the alarm triggers. You can choose between a chime-style alert mode and a louder alarm mode using the included side switch. That makes it easier to tailor your routine, for example using one mode for daytime monitoring and the other for when you want maximum deterrence.
Key features that affect everyday use
120dB siren for deterrence and awareness
The audible output is rated at 120 decibels, which is one reason buyers describe it as clearly audible from other rooms. If your main goal is to create an immediate sound when an entry point opens, this model is built for that purpose.
Chime vs alarm is adjustable, but not subtle
The system includes an easy-access switch that lets you select either a chime alert or the full alarm sound. Buyers who installed these specifically for the chime feature often found the “chime” less like a neutral notification and more like a very loud, high-pitched blast. If you want quiet reminders, you may find the sound level and tone too much, especially when installed near bedrooms or frequently used rooms.
Wireless, indoor mounting with double-sided tape
Installation is designed to be quick and tool-free. The alarms mount indoors using the included double-sided tape, and they are intended for use where you can place the main unit and magnet so they line up properly when the door or window is closed.
Battery-powered convenience
Each alarm operates on four included LR44 batteries, and there is a front LED low-battery indicator. Since there is no app or hub, the LED indicator is your main heads-up that it is time to replace batteries.
Who this is best for
- Apartment, dorm, or office setups: a no-monthly-fee way to add audible alerts to likely entry points.
- People who want immediate sound, not phone notifications: you hear the alert directly when something opens.
- Families adding extra awareness for doors, windows, drawers, and cabinets: useful when you want a reminder signal for everyday access points.
- DIY shoppers looking for a straightforward upgrade: magnetic contact sensing plus a loud siren in a small, wireless format.
Who should consider a different option
- Buyers who need a truly quiet chime: the chime mode may be too high-pitched and disruptive for some homes.
- Shoppers who want smart home integration: this system is not smart home compatible.
- Anyone who needs outdoor-rated placement: installation is intended for indoors, so you will want to plan your mounting accordingly.
Pros and cons, in plain terms
Overall, it is a simple, loud, DIY entry-point alarm kit. The most compelling strength is the high-volume 120dB siren combined with fast, wireless setup. The main tradeoff is that the chime mode is not “soft,” so it is better viewed as a secondary alert setting rather than a gentle doorbell-like tone.
Price and availability
This 6-pack is positioned as an affordable add-on to home awareness. Prices and stock can change quickly, so it is worth checking the latest listing for current cost and availability.
